-Spirit of Daytona had the second gear break in its new No. 90 Corvette DP early in Sunday morning’s session.

-Action Express Racing faces a triple learning curve for the 2012 Rolex 24. In addition to the new Corvette DP bodywork, the 2010 Rolex 24-winning team also has a new engine (Earnhardt Childress Racing Chevrolet) and a new chassis (Coyote). Team director of team operations Elton Sawyer said the biggest challenge at the Roar has been working with brake temperatures.

-APR Motorsport brought four different cars to the Roar – in three different classes. The team is debuting in the Rolex Series with the No. 51 Audi R8 GRAND-AM.
